Access controller based on Loongson chip

The invention provides an access controller based on a Loongson chip. The domestic Loongson LS1B chip is taken as a main control unit (MCU); the MCU is connected with all functional modules, respectively. The use of the Loongson chip breaks the monopoly of foreign access controller MCU manufacturers, the security of use is improved, and the requirement on high security level can be met. Functionally, access control is realized on four doors; a card reader interface supports wiegand signals in two formats wiegand26 and wiegand34, and meanwhile, is capable of supporting door opening manners including a single-person recognizing door opening manner, a two-person recognizing door opening manner and a two recognition method combined door opening manner, and also achieves the function of preventing sneaking and forced password door opening. The access controller is in communication with an upper computer by use of a TCP/IP (Transmission Control Protocol/Internet Protocol) Ethernet manner; the access controller is capable of communicating with matched access management software, and achieves the functions of online controller search, controller parameter configuration, real-time data uploading, historical data uploading, remote restart and the like.
